Containing an Essay upon SOLIDS and Artificers Work;

Wherein not only the practical Methods of measuring Boards,Round Timber, Bricklayers and Plaisterers Work ; but also Marl-pitsand Hay are rendered plain and easy; the Whole being illustratedwith peculiar Explanations, Rules, Examples and Operations.

SECT. I.

A Surveyor is (by most Country People} looked upon asunqualified for hisProfelsion if he be unacquainted with Stereometry,to wit, a Branch of the Mathematics, which treats particularlyabout the Mensuration of Solid Bodies ; and therefore, that thisTreatise may be rendered every " ay useful for the Country Man(for whom it is chiefly intended) I have herein given some necessaryRules and Directions (with regard to real Practice) how to measureBoards, round Timber, Bricklayers and Plaisterers Work, togetherwith the practical Methods of measuring Marl-pits and Hay, andfirst of

Board Measure.

Boards, according to the general Method are measured by takingthe Length and Breadth thereof in Feet and Inches, and to findthe Content observe this

Rule : Multiply the Length by the Breadth, and the productis the Content.

Note, 12 Inches make one Foot in Length, 144 Square Inches,one Square Foot, and 400 Square Feet, one Rood of Boards.

Note, Also, in taking the Length of a single Board or Log ofBoard*, any thing under six Inches is seldom noticed.
